Experience is presented with eight operations for pectus carinatum. Deformities of the chest with prominence of the sternum (pectus carinatum) are less frequent than those with a depressed sternum (pectus excavatum). Surgical correction is indicated for psychological if not for physiological reasons. There are two main types of sternal prominence, the chondromanubrial and the chondrogladiolar. Different operative techniques are required for their correction. These involve resection of the cartilages which are in malposition and suitable osteotomies on the sternum.
